Topic: Advancements in Variational Data Assimilation

Friday, February 2, 2024 from 08-10 UTC (***SPECIAL TIME***)

Organisers and Conveners: Massimo Bonavita (ECMWF, UK),  Ross Bannister (University of Reading, UK), Ting-Chi Wu (CWB, Taiwan), James Taylor (RIKEN, Japan)

Join us in a deep dive into the world of Variational Data Assimilation. This session is dedicated to exploring new frontiers in variational methods, crucial for the advancement of data assimilation across diverse domains. We welcome contributions that shed light on recent developments, tackle complex challenges, and demonstrate the wide-ranging applications of variational data assimilation, pushing the boundaries and efficiency in predictive modeling.
